I'm trying to find out where I can find or how I can make an elastic cytoplasm film.It will be used as a separation between two chambers with a different (changing) air pressure, this means the film needs to be elastic to move in and outward.

I don't know what a "cytoplasm film" would be. A black membrane system comes to mind, in which a planar phospholipid bilayer is formed by painting the phospholipids across a small aperture in a rigid sheet separating two chambers containing aqueous solutions. Such a system cannot withstand pressure differentials across the membrane, the planar lipid simply bows and pops. However, you cite a "cytoplasm film" separating the chambers rather than a membrane. What would such a film consist of?

Thank you for the answer! Indeed, a membrane is a better word for what I am looking for, English isn't my native tongue.The membrane should be elastic, but it would be fine if this membrane pops now and then (an average of 2 months lifespan would be great!)I'm somewhat a leek in biology so it is a bit harder for me to fully understand what is said.The membrane should consisted of cytosplasm, I have absolutely no idea how to accomplish this, but I know it is possible.
